After heavy rains, the Limpopo river in southern Mozambique has burst its banks, causing floods that have driven more than 150,000 people from their homes and killed at least 38, according to a UN official on Tuesday.

The inundation's devastating sprawl is clear in these false-colour images of the town of Chokwé taken by NASA's Terra satellite. They show infrared, red and green wavelengths of light. Below, the vegetation of the region's fields is deep green in an image from February 2005. Above, an image taken on 25 January this year - a few days after the river at Chokwé was logged at 5.6 metres above normal - shows that same farmland inundated with muddy water, here coloured lavender and pink.
